Associations between diet, physical activity and body fat distribution: a cross sectional study in an Indian population.

BACKGROUND: Obesity is a growing health problem in India and worldwide, due to changes in lifestyle. This study aimed to explore the independent associations between dietary and physical activity exposure variables and total body fat and distribution in an Indian setting. METHODS: Individuals who had participated in the Indian Migration Study (IMS) or the Andhra Pradesh Children And Parents' Study (APCAPS), were invited to participate in the Hyderabad DXA Study. Total and abdominal body fat of study participants was measured using DXA scans. Diet and physical activity (PA) levels were measured using questionnaires. RESULTS: Data on 2208 participants was available for analysis; mean age was 49 yrs in IMS, 21 yrs in APCAPS. Total energy intake was positively associated with total body fat in the APCAPS sample: a 100 kcal higher energy intake was associated with 45 g higher body fat (95% CI 22, 68). In the IMS sample no association was found with total energy intake, but there was a positive association with percent protein intake (1% higher proportion of energy from protein associated with 509 g (95% CI 138,880) higher total body fat). Broadly the same pattern of associations was found with proportion of fat in the abdominal region as the outcome. PA was inversely associated with total body fat in both populations (in APCAPS, one MET-hour higher activity was associated with 46 g (95% CI 12, 81) less body fat; in the IMS it was associated with 145 g less body fat (95% CI 73, 218)). An inverse association was observed between PA and percentage abdominal fat in the IMS but no association was seen in the APCAPS population. CONCLUSIONS: In this Indian population, there was an inverse association between PA and body fat. Associations between body fat and dietary variables differed between the younger APCAPS population and older IMS population. Further longitudinal research is needed to elucidate causality and directions of these associations across the life course

Training the gynecologic oncologists of the future: challenges and opportunities

Several recent advances in gynecologic cancer care have improved patient outcomes. These include national screening and vaccination programs for cervical cancer as well as neoadjuvant chemotherapy for ovarian cancer. Conversely, these advances have cumulatively reduced surgical opportunities for training creating a need to supplement existing training strategies with evidence-based adjuncts. Technologies such as virtual reality and augmented reality, if properly evaluated and validated, have transformative potential to support training. Given the changing landscape of surgical training in gynecologic oncology, we were keen to summarize the evidence underpinning current training in gynecologic oncology.In this review, we undertook a literature search of Medline, Google, Google Scholar, Embase and Scopus to gather evidence on the current state of training in gynecologic oncology and to highlight existing evidence on the best methods to teach surgical skills. Drawing from the experiences of other surgical specialties we examined the use of training adjuncts such as cadaveric dissection, animation and 3D models as well as simulation training in surgical skills acquisition. Specifically, we looked at the use of training adjuncts in gynecologic oncology training as well as the evidence behind simulation training modalities such as low fidelity box trainers, virtual and augmented reality simulation in laparoscopic training. Finally, we provided context by looking at how training curriculums varied internationally.Whereas some evidence to the reliability and validity of simulation training exists in other surgical specialties, our literature review did not find such evidence in gynecologic oncology. It is important that well conducted trials are used to ascertain the utility of simulation training modalities before integrating them into training curricula.</p

Candida dubliniensis candidemia in patients with chemotherapy-induced neutropenia and bone marrow transplantation.

The recently described species Candida dubliniensis has been recovered primarily from superficial oral candidiasis in HIV-infected patients. No clinically documented invasive infections were reported until now in this patient group or in other immunocompromised patients. We report three cases of candidemia due to this newly emerging Candida species in HIV-negative patients with chemotherapy-induced immunosuppression and bone marrow transplantation

Simultaneous localisation and mapping on a multi-degree of freedom biomimetic whiskered robot

A biomimetic mobile robot called “Shrewbot” has been built as part of a neuroethological study of the mammalian facial whisker sensory system. This platform has been used to further evaluate the problem space of whisker based tactile Simultaneous Localisation And Mapping (tSLAM). Shrewbot uses a biomorphic 3-dimensional array of active whiskers and a model of action selection based on tactile sensory attention to explore a circular walled arena sparsely populated with simple geometric shapes. Datasets taken during this exploration have been used to parameterise an approach to localisation and mapping based on probabilistic occupancy grids. We present the results of this work and conclude that simultaneous localisation and mapping is possible given only noisy odometry and tactile information from a 3-dimensional array of active biomimetic whiskers and no prior information of features in the environment

Estimation method for evaluating the wave-induced flicker level emitted by a tidal energy farm

International audienceThe inherently fluctuating nature of sea waves can be reflected to a significant extent in the power output of tidal turbines. However, these fluctuations can give rise to power quality issues such as flicker. Hence, it is important to assess the impact which tidal farms may have on their local network before such power plants are allowed to connect to the grid. This paper analyses under which sea-state and grid conditions a 30 MW rated tidal farm breaches the grid code requirements in terms of short-term flicker level. Then, it describes a simplified method for estimating the flicker level by means of an equivalent sinusoidally-modulated voltage profile

Concepts of mental disorders in the United Kingdom : Similarities and differences between the lay public and psychiatrists

BACKGROUND: The lay public often conceptualise mental disorders in a different way to mental health professionals, and this can negatively impact on outcomes when in treatment. AIMS: This study explored which disorders the lay public are familiar with, which theoretical models they understand, which they endorse and how they compared to a sample of psychiatrists. METHODS: The Maudsley Attitude Questionnaire (MAQ), typically used to assess mental health professional's concepts of mental disorders, was adapted for use by a lay community sample (N = 160). The results were compared with a sample of psychiatrists (N = 76). RESULTS: The MAQ appeared to be accessible to the lay public, providing some interesting preliminary findings: in order, the lay sample reported having the best understanding of depression followed by generalised anxiety, schizophrenia and finally antisocial personality disorder. They best understood spiritualist, nihilist and social realist theoretical models of these disorders, but were most likely to endorse biological, behavioural and cognitive models. The lay public were significantly more likely to endorse some models for certain disorders suggesting a nuanced understanding of the cause and likely cure, of various disorders. Ratings often differed significantly from the sample of psychiatrists who were relatively steadfast in their endorsement of the biological model. CONCLUSION: The adapted MAQ appeared accessible to the lay sample. Results suggest that the lay public are generally aligned with evidence-driven concepts of common disorders, but may not always understand or agree with how mental health professionals conceptualise them. The possible causes of these differences, future avenues for research and the implications for more collaborative, patient-clinician conceptualisations are discussed.Peer reviewedFinal Accepted Versio

The Effect of Combat Exposure on Veteran Homelessness

This paper examines the effect of combat exposure on homelessness in surviving deployed veterans. We assess combat exposure in 50,522 Millennium Cohort Study (MCS) participants by combining self-reports of witnessing death through the 2011–2013 survey cycle with military deployment records since September 2001. We use participants’ 2014–2016 MCS survey cycle reports to assess subsequent homelessness. We accommodate uncertainty surrounding limited data with an information theoretic, semi-parametric Generalized Maximum Entropy model. We estimate, on average, a single combat exposure increases the probability of homelessness by about 0.40 percentage points (27 percent relative to the mean probability) and multiple combat exposures increase the probability of homelessness by about 0.57 percentage points (38 percent relative to the mean probability). Our model also sheds light on pre-deployment characteristics associated with combat exposure resilience; estimates indicate veterans with poorer predeployment mental or physical health and veterans under the age of 30 years are less resilient to the effects of combat exposure on homelessness. Cost calculations with model estimates suggest combat exposure contributed to 4,600 veterans experiencing homelessness and $54 million in related public spending.The Millennium Cohort Study is funded through the Military Operational Medicine Research Program of the U.S. Army Medical Research and Materiel Command, Fort Detrick, Maryland.

Wave-induced flicker level emitted by a tidal farm

International audienceThe inherently fluctuating nature of sea waves can be reflected to a significant extent in the power output of tidal turbines. However, these fluctuations can give rise to power quality issues such as flicker. Hence, it is important to assess the impact which tidal farms may have on their local network before such power plants are allowed to connect to the grid. This paper describes the influence of the wave climate on the short-term flicker level induced by a tidal farm on the point of common coupling. It analyses also under which conditions the tidal farm breaches the grid code requirements in terms of short-term flicker level

The SED Machine: a robotic spectrograph for fast transient classification

Current time domain facilities are finding several hundreds of transient astronomical events a year. The discovery rate is expected to increase in the future as soon as new surveys such as the Zwicky Transient Facility (ZTF) and the Large Synoptic Sky Survey (LSST) come on line. At the present time, the rate at which transients are classified is approximately one order or magnitude lower than the discovery rate, leading to an increasing "follow-up drought". Existing telescopes with moderate aperture can help address this deficit when equipped with spectrographs optimized for spectral classification. Here, we provide an overview of the design, operations and first results of the Spectral Energy Distribution Machine (SEDM), operating on the Palomar 60-inch telescope (P60). The instrument is optimized for classification and high observing efficiency. It combines a low-resolution (R$\sim$100) integral field unit (IFU) spectrograph with "Rainbow Camera" (RC), a multi-band field acquisition camera which also serves as multi-band (ugri) photometer. The SEDM was commissioned during the operation of the intermediate Palomar Transient Factory (iPTF) and has already proved lived up to its promise. The success of the SEDM demonstrates the value of spectrographs optimized to spectral classification. Introduction of similar spectrographs on existing telescopes will help alleviate the follow-up drought and thereby accelerate the rate of discoveries.Comment: 21 pages, 20 figure
